As you know has been discovered in recent days a serious bug in iOS SSL connections that would potentially access sensitive data that supposedly would be criptografados.
So Apple has released an update to fix the problem with iOS 7.0.6 and iOS 6.1.6. Then Evasi0n7 has also released the update to iOS 7.0.6 Jailbreak.
Although it would be highly recommended to upgrade to iOS 7.0.6 remember that in principle lose the jailbreak tweak installed and should first update since iOS and only in a second moment we could reapply through Jailbreak Tool Evasi0n7. All this obviously can be a bit tedious for those who have done the jailbreak on their devices.
Therefore Ryan Petrich, famous developer Jailbreak scene, has released a tweak that solves the failure of iOS but without having to upgrade to iOS 7.0.6.
The tweak is called SSLPatch and you can find it in the repo http://rpetri.ch/repo/
(probably you will have it added to the sources if you have installed any tweak as Activator, BioLockdown or FlipControlCenter).
